copysign 将第二个参数中的值的符号复制到第一个参数中的值 greater, greater_equal, less, less_equal, equal, not_equal 执行逐个元素的比较,产生布尔数组(等同于中缀运算符>, >=, <, <=, ==, !=) logical_and 计算逻辑与(&)的逐个元素真值 logical_or 计算逻辑或(` logical_xor 计算逻辑异或(^)的...
greater大于。greater_equal大于等于。less小于。less_equal小于等于。equal等于。not_equal不等于。logical_and逻辑与(&)。logical_or逻辑或(|)。logical_xor逻辑异或(^)。基本数组统计方法 名称说明sum对数组中全部或者是某个轴向的所有元素进行求和。零长度的数组的sum值为0。mean算术平均值。零长度的数组的mean值...
In these examples, it’s important to note that the order in which the data is stored in the login tuple is critical because something like ("john", "secret") isn’t equal to ("secret", "john") in tuple comparison even if they have the same items....
Changing the version specifier for the requests package ensures that any version greater than or equal to 3.0 doesn’t get installed. The pip documentation provides extensive information about the requirements file format, and you can consult it to learn more....
The following command tells Python to associate the code name or variabletownwith the name of a town called "Contosoville." For this command, you use the assignment equal sign (=) operator. Anytime after this command, when Python sees the variabletown, it will substitute the value "Contoso...

Theroundroutine implements the most common method of rounding, which is also known assymmetric arithmetic rounding. It returns the nearest integer that corresponds to the given floating-point value. If the fractional part of an input value is equal to or greater than 0.5, then the resulting inte...
>>> 1 < 1 # 1 is not greater than 1 False >>> 1 <= 1 # 1 is lesser or equal to 1 True >>> 2 >= 3 # 2 is not greater or equal to 3 False For the first line of code, the order of the dictionary items is different but unlike the list in the second line of code, ...
WebDriverWait配合该类的until()和until_not()方法,根据条件灵活的等待 程序每隔xx秒看一眼,如果条件成立了,则执行下一步,否则继续等待,直到超过设置的最长时间,然后抛出TimeoutException。 显式等待是你在代码中定义等待一定条件发生后再进一步执行你的代码。
